Western civilization in the turn of the century in spite its scientific & technological advance has become the menace of this planet rendering it soon an inhabitable place.
Industrial revolution instead of feeding and clothing the needy it is drying up all recourses in the name of capital gain.
Religious beliefs and dogmas instead of bringing humans closer to themselves and  as a natural outcome to one another has separated them and often guide them into destroying one another.
Whenever a civilization reaches a dead-end it goes back to the Archaic trying to get it all reconnected trying to see where did it all go wrong.
The base of western civilization as we know it is Ancient Greece and perhaps the person responsible for its spread on a wider or even global for the time being scale was Alexander the Great. Alexander was a pupil of Aristotle the philosopher the one that advanced Greek maxims  such as “Nothing in excess”, ’’It is better to do everything in moderation”, “ Know thy self” into a full philosophical system, known in brief as the “Golden Mean”.
Aristotle’s basic concept that “virtue is the desirable middle between two extremes” (one of excess and the other of deficiency), became the foundation of his philosophical system, that should be applied to all aspects of human life, thus reiterating on Protegra’s’ maxim that

“Man should be the measure for all things”.

Under Aristotle, Alexander was exposed to the teachings of all Greek thinkers, regardless of tribe, including Thracians, the few Spartans and all Ionians. 
Many of Alexander’s decisions and actions testify the Aristotelian influence:
He set free each city he occupied.                                                                     
If a different religion was worshiped, he allowed its free practice.If they were slaves, he gave them freedom. Parenthetically, Aristotle too, through his will, set free his personal slaves.If people were virtuous, he would consider them Greeks, not barbarians, implying, therefore,that his main pursuit was to spread the Greek culture and civilization to all nations.
This brings us into a vital question

“Had the Great King lived longer, thus allowing changes to be integrated, would human activity on our planet have followed a different path”?
 If so, how or why?
